Islam is not a "religion of peace". That's just a vapid defense that people say to absolve Muslims of association with any violence.
IMO Islam is a religion based on PURE HATE and VIOLENCE against women and anyone not following its teachings.
Are any religions truly peaceful? Not that I've ever heard of - Christianity especially.
I have heard that paganism is about peace and nature, but even they must have some extreme pagans who are not peaceful.
The only organized religion I've encountered that truly practices the peace that it preaches is Jainism. Check it out for yourself.
Islam seems to prove every day it is utterly incapable of peace, even amongst its own followers. Try speaking out against it or it's holy book in public, you may well find yourself the target of death threats...by followers of the alleged religion of peace.
Basically they were forced to.
The first war they could not do anything until Allah gave them permission to fight.
It was self defense.
The only time it was not self defense was when they took control of Mecca ( And there was special resons for that too.)
Islam is the most violent religion ive ever heard of. I think their book that they live by talks about cutting the heads off of infidels.
Most religions have waged war against each other, it says to do so in most holy scriptures.
